I am sure that the first thing that pops into your head when you read those words are passages from Shakespeare's works, and words like "thou" and "ye".
I am afraid, however, that you are incorrect. The English that Shakespeare used is actually called Early Modern English.
Old English was a language spoken by the Anglo-Saxons (or English speaking peoples) who inhabited Britain from around 449-1066, and modern day languages spoken all over the world can trace their roots back to this dialect. It looks and sounds completely different then any of these languages however.
So foreign is it to our ears in fact, that elements of these ancient words were used to make up the Elfish language in Tolkien's Lord of The Rings books and movies. Here's an example of Elfish:
Because literacy was low, stories and histories were transmitted orally at the time and so there are only a few texts that exist in Old English. One of the most famous (other than the Bible of course) is Beowulf — yes, that long, epic poem that you were forced to study in English class, and didn't really understand, was actually a translation from Old English.
Here are lines 115-125 of the poem, when Grendel the monster attacks while the troops are sleeping, as you may have remembered reading them:
Now here is what you just read being spoken in Old English (the text that you see in the video are the lines above written in Old English):
Pretty crazy isn't it!
How do I know about this you ask? I studied it. Yup I took an entire class in university on learning how to speak, read, and translate this old version of my own language.
If you want to lean more, I suggest Introduction To Old English by Peter S. Baker, and picking up a version of Beowulf in it's original form. I like the version by Bruce Mitchell and Fred C. Robinson.
